Answer:
<em>2x - 1</em>
Step-by-step explanation:
<u>Equivalent Algebraic Expressions
</u>
One algebraic expression can be written in several ways by applying known rules and theorems that modify expressions without changing its final value.
The expression:
1 + 2(x - 1)
Can be modified by applying the following operations:
Multiplying the constant by the contents in parentheses:
1 + 2x - 2
Collecting like terms:
-1 + 2x
Or, equivalently:
2x - 1
Answer:
Hi there!
Your answer is:
No, p= 3 is <u>not</u> a solution for this equation!
Step-by-step explanation:
4(3) = 24 ???
4×3 = 24?
12 = 24??
NO. 12 does <u>NOT</u> equal 24!
Hope this helps
Answer:
1. D 2. A 3. Distribute the four in 4(x+1)
Step-by-step explanation:
1. It says that Jamie is saying that they are "not equivalent".
2. You have to use the distributive property to distribute the 4 to x and to the 1.
3. After distributing, compare the two expressions and now see if they are equivalent or not.
Answer:
a) 0.25
b) 52.76% probability that a person waits for less than 3 minutes
Step-by-step explanation:
Exponential distribution:
The exponential probability distribution, with mean m, is described by the following equation:
In which 
is the decay parameter.
The probability that x is lower or equal to a is given by:
Which has the following solution:
The probability of finding a value higher than x is:
In this question:
a. Find the value of λ.
b. What is the probability that a person waits for less than 3 minutes?
52.76% probability that a person waits for less than 3 minutes
